My car would be in bits if I took it to Calder!

The 040 and 044 pumps are not E compatible according to Bosch, having said that, there are a large number of cars that run them (mine included) that do not seem to have an issue. A solution to this could be two separate lift pumps (such as these http://www.efihardware.com/products/261/lift-pump-340hp-Rollercell) drawing from each side of the tank using the pickup for the lift pump as well as the standard pickup.

Why are you wanting to use AN fittings?

Winton rewards cars that have drive out of the corners and good mid corner speed, both things that the Nissan's are supposed to have a lot of, but as others have said, they don't have the top end speed still, but that isn't as much of an issue at Winton as anywhere else on the calender.

If you only have a lift pump on one side of the tank (due to the that being siting over the propshaft, there is a hump in the bottom of it) and the jet pump is not working, then you have to rely on the movement of the car to transfer fuel from one side of the tank to the other, so if you are going around a corner and this causes the fuel to move to the other side of the tank to where the lift pump is then it is possible to either not be able to get the full amount of fuel out of the tank, and dependent on the size of your surge tank, the pumps used and the engines fuel consumption, then it could also be drained. If that is the in tank side, then no, they usually just spray into the tank from the nozzle to remove any possibility of flow restriction, the two moldings into it are the return from the fuel rail (center) and lift pipe (outside edge)

If the jet pump in a Skyline is anything like the jet pump in a WRX fuel tank, then it is used as a venturi effect pump to transfer fuel from the other side of the hump in the bottom of the fuel tank. It works by using the return line pressure to create a lower pressure in the suction pipe, this draws the fuel out of the otherside of the tank and deposits into the side where the fuel pump pick up is. These units are used for a number of reasons in that they are cheap, self priming, very low maintenance and also very cheap. The problems that can occur with them are when you use larger injectors and greater IDC's, there may not be enough pressure and volume in the return line to the tank to drive the pump. If you imagine that the compressed air is the return line and the vacuum is the line from the other side of the tank, then this give a visual idea of what is happening.

Check SpeedFlow as well, they have a new series of adapters like this as well, they don't seem to come up on the website, but their product code is 912-M18-02-BLK for a M18x1.5 and 1/8"NPT adapter.

It has always been recommended to me by the hose suppliers that with the 400 series barb fittings a secondary clamp (such as the cobra clamps that are designed specifically for these types of fittings) is used, on any hose that will see over 40psi or temps over 60 degrees. They are supposed to cope without one, but if there is any movement in the lines, it can lead to them becoming loose.

Translation, "They are not paying me enough to go back to that dump"

Race Three

I saw your spare gearbox at Trackart yesterday Snowy, no wonder your Veyron weighs so much, the gearbox is massive.

I should have the cage bracket tomorrow Snowy, I'll drop it off at RacePace.

Also, having the 95dB noise limit adds $2,000+ to the bill.

Protectionism, they do not want to see an upstart category from nowhere making their own series look bad.

Never realised that a Ford Focus was a GT car...

The FIA international series rules unfortunately do not allow them to run in Europe.

Part of the reason for the price increase ( and number of cars) is that it is also a round of the CAMS sprint championship, hence the 95dB allowance.

I was a dealer for these products till the end of last year, the constant underselling from the UK changed that.

Probably because the dealer buy price is higher than you paid direct.

Did you buy it from the UK direct?

Still has the spider gears, unless it is a Torsen style diff.

I've seen that occur before, Rich, the issue ended up being caused by the bearings on the spider gears in the diff seizing due to a lack of oil and the oil in the diff failing from overheating, so that when the diff was under load in a corner, the spiders moved out of alignment and wedged in the case, causing inconsistent load to go through the wheels.

Your mid and exit corner speed out of the last corner onto the straight plays a major part in your terminal speed at the end of the straight, I have about 110kW atw in the Speads, but I'll hit 260+ at the end of the main straight at PI due to coming off of the last corner well.

KB most likely, as they have to submit the lists to the timing people and CAMS with enough time for all of the checks and data entry to be done.

Probably has the best suspension to cope with the bumps as well.
